Delta’s CRJ-200s are operated as Delta Connection by regional affiliates on short-haul segments in the domestic and North American markets. The CRJ-200 accommodates 50 passengers in a one-class configuration (though the bulkhead seats are sold as Delta Comfort+ in spite of the fact they have the same legroom as all other rows).
This is a regional jet, which is smaller than Delta mainline aircraft. Flights on Delta Connection affiliates are sold as Delta tickets, appear as Delta flights on reservations (it will say “Operated by [insert regional affiliate]” in small letters). The cabins are smaller and overhead space is limited. Passengers might have to leave larger rollaboard luggage on the jet bridge. These carry ons are not checked through to your final destination and can be retrieved on the jet bridge after the flight. Do not enter the terminal until bags have been delivered.
